GreatSchools Rating
The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.

I think that COHS is a very competitive school to go to, with many cool teachers that greatly prepare you for college. Most AP teachers have very good pass rates for AP exams, a clear sign of how ready most of our students are for college, and our college admissions are reflected as such.

On the flip side, the worst part is the food, it's always dry and the pizza is oiled like a car .

Lots of fights, many students vaping in the bathrooms. Very few teachers who actually care about students.

Knowing what I know now, and seeing my daughter's progress in a different local high school, I would not have sent my learning disabled son to Cosumnes Oaks High School. I recommend that other parents of learning disabled students look elsewhere as well.

If you are struggling they most likely will help guide you in the right direction. The campus is very nice and for the most part very well maintained. They ha...
